In partial occlusion problem, we have many methods for gait identification. However, based on Gait Energy Image (GEI) part, they are hardly occluded local part threshold problem. We propose an adaptive local module weight to reduce score of the occluded part. The adaptive local module weight is constructed from a consensus and a complementary principles of global and local modules. Firstly, we construct...
This paper proposes tone model enhancement for low complexity tone recognition. The tone model reduces the number of input frames by estimating fundamental frequency (F0) from only estimated vowel signals, called vowel magnitude difference function, vowel-MDF (VMDF). Accordingly, it reduces F0 negative influence from neighboring syllables in continuous speech. We enhance tone recognition accuracy...
A tone classifier is an essential part of an automatic tonal speech recognizer (ATSR) because tonal languages recognize word meaning by tones. However, many researchers have developed a highly efficient tone recognition by using rich mathematical techniques and used the whole input speech as an input of pitch detection process. This paper proposes a reduced complexity tone classifier for the automatic...
In this paper, efficient model estimation based on particle filter for visual object tracking in automated video surveillance is proposed. Particle filter is used for our object prediction. We try to reduce complexity of particle filter by embedding non-stationary Gaussian object model into particle filter algorithm in that the dimension of the object state can be reduced. The object model is based...
Tone classification function is used for improving recognition accuracy in tonal speech recognizer (TONE-SPEC). Although average magnitude difference function (AMDF) is generally used to find pitch period of fundamental frequency, there are many frame-repeated processes. This paper proposes scalable architecture of tone classification function for tonal speech recognizer. In the proposed architecture,...
Vessel segmentation is very important in an automatic screening system for fundus images. Vessels are often segmented and removed from retinal images before the other residual lesions are detected. Incomplete vessel removal usually causes a false positive in lesion detection, especially for Microaneurysms detection. Segmenting vessels in spatial image domain makes miss detection due to non illumination...
In non-destructive granular material dielectric measurement, microwave cavity resonator technique which is dependent against varied size and shape of cavity is suitable. Since the transmitted microwave should equally cover around the shape, system design is needed to consider transmitted microwave equally covering all area of cavity. This paper proposes a system of microwave cylindrical cavity resonator...
This paper proposes a VT-AMDF pitch detection algorithm which based on average magnitude difference function (AMDF). Time processing is important when implement in real time system. In order to decrease computational time and complexity of pitch detection, the VT-AMDF uses only 55% of total time intervals. The method can reduce the computational time 1.3, 1.4, 4.8 and 5.4 times, compared with original...

For the operational steps, three spontaneous thermal features of a vehicle consist of the windscreen, radiated heat from the...
Tonsillitis disease is the cause of heart attack and pneumonia. It is also a sign of suspected symptom of heart disease. To improve data transfer rates, this paper proposes VLSI architecture by using color model for early-state tonsillitis detection. In this method, input image is divided into 9 blocks. Each block has 3times3 window which send color data and pixel address to computation box. The system...

This paper proposes an architecture of HMM-based isolated-word speech recognition with tone detection function. In this architecture, tone detection function is added...
The moisture content inspection for agriculture material is very necessary to make a quality control. Since the amount of the soybean meal, which can transmute into animal food, is very plenty and the distribution of moisture is difference. Therefore, the non-destructive moisture inspection is difficult to perform. This paper proposes microwave free-space measurement using the resonance cavity. Measuring...
